Emerging Trends in Active Packaging for Food: A Six-Year Review
Andrade, Mariana A.; Barbosa, Cássia H.; Ribeiro-Santos, Regiane; Tomé, Sidney; Fernando, Ana Luísa; Silva, Ana Sanches; Vilarinho, FernandaThe development of active food packaging has evolved rapidly in recent years, offering innovative solutions to enhance food preservation and safety while addressing sustainability challenges. This review compiles and analyzes recent advancements (2019–2024) in release-type active packaging, focusing on essential oils, natural extracts, and phenolic compounds as active agents. Primarily plant-derived, these comp...
Extension of Poultry Meat Shelf Life Using Cynara cardunculus L. Leaf Extracts ...
Barbosa, Cássia H.; Andrade, Mariana A.; Vilarinho, Fernanda; Silva, Ana Sanches; Fernando, Ana LuísaFood additives are used to prevent food spoilage and extend its shelf life. However, con cerns regarding the potential health implications associated with some synthetic additives have prompted research efforts aimed at identifying natural alternatives, such as plant extracts. Cynara cardunculus L. (cardoon) is known for its antimicrobial and antioxidant properties. The aim of this study was to evaluate the cap...
Active Low-Density Polyethylene-Based Films by Incorporating α-Tocopherol in th...
Azevedo, Ana G.; Barros, Carolina; Miranda, Sónia; Machado, A. V.; Carneiro, O. S.; Silva, Bruno; Andrade, Mariana A.; Vilarinho, FernandaIn this work, alpha-tocopherol (α-TOC) was encapsulated in poly(lactic acid) nanoparticles (PLA NPs) and added to low-density polyethylene (LDPE) films with the aim of producing an active film for food packaging applications. PLA NPs loaded with α-TOC were produced through nanoprecipitation and dried using two methods (freeze-dryer and oven). LDPE-based films with final polymeric matrix concentrations of 10 and...
Blown film of PLA for packaging with green tea and fish industrial residues: an...
Rodrigues, Pedro António Veiga; Cunha, Ana B.; Andrade, Mariana A.; Vilarinho, Fernanda; Machado, Ana Vera; Castro, Maria Cidália RodriguesThe use of food waste on the production of packaging can be seen as a promising strategy to cost reduction and new properties. Moreover, packaging, besides food physical protection, should establish a barrier to light and oxygen together with antioxidant and antibacterial activity, to extend the shelf-life of perishable products. In this study, PLA films with the incorporation of natural additives (cold fish pr...
Effect of pomegranate peels and extract in barrier, optical and mechanical prop...
Andrade, Mariana; Vilarinho, Fernanda; Rodrigues, Pedro; Barros, Carolina; Cruz, Vasco; Machado, Ana Vera; Barbosa, Cássia; Ramos, FernandoBeing more than 50 % of pomegranate (Punica granatum L.) constituted by non-edible parts, namely peels (50%) and seeds (10%), pomegranate is an excellent source of by-products. Its peels and seeds present excellent antioxidant and antimicrobial activities and a high content of phenolic compounds, namely ellagitannins. This work aimed to evaluate the mechanical and optical properties of two polylactic acid (PLA)...
Antioxidant and antimicrobial properties of PLA based active packaging with pom...
Andrade, Mariana; Rodrigues, Pedro; Barros, Carolina; Cruz, Vasco; Machado, Ana; Barbosa, Cássia; Coelho, Anabela; Furtado, Rosália; Correia, CristinaActive food packaging’ primary goal is to extend foodstuffs’ shelf life, through a dynamic and continuous interaction between the package and the packaged food. In an emission active packaging, the objective is the gradual release of antioxidant and/or antimicrobial compounds into the food surface, to delay the natural foods’ degradation. The active compounds can be extracted from several sources, such as aroma...
Extending High Fatty Foods Shelf-Life Protecting from Lipid Oxidation and Micro...
Andrade, Mariana A.; Rodrigues, Pedro V.; Barros, Carolina; Cruz, Vasco; Machado, Ana Vera; Barbosa, Cássia H.; Coelho, Anabela; Furtado, RosáliaThe search for new forms to extend foodstuffs’ shelf-life through the use of natural compounds and extracts continues to grow among researchers and the industry. In this line of thought, the main objective of this work was to develop, characterize and evaluate the effectiveness of an active food packaging based on polylactic acid (PLA) and incorporated with natural extracts obtained from grape and/or pomegranat...
LDPE and PLA Active Food Packaging Incorporated with Lemon by-Products Extract:...
Andrade, Mariana A.; Barbosa, Cássia H.; Mariño-Cortegoso, Sandra; Barbosa-Pereira, Letricia; Sendón, Raquel; Buonocore, Giovanna G.Low-density polyethylene-based packaging with 4% lemon extract (LDPE/4LE) and two polylactic-based (PLA) packaging materials with 4% and 6% lemon extract (PLA/PEG/4LE and PLA/6LE) were produced. O2 and water permeability tests were performed, the total and individual phenolic compounds content were measured, and the films' antioxidant activities were determined. The films' ability to delay lipid oxidation was t...

PLA films loaded with green tea and rosemary polyphenolic extracts as an active...
Andrade, Mariana A.; Barbosa, Cássia H.; Cerqueira, Miguel A.; Azevedo, Ana Gabriela; Barros, Carolina Lemos; Machado, A. V.; Coelho, AnabelaIn the present study, RE presented higher antioxidant capacity and higher content of total phenolic compounds than GTE. While the main phenolic compounds identified in RE were carnosic acid, carnosol and rosmarinic acid, in GTE catechins, rutin and gallic acid were the main identifies compounds. Extracts were incorporated into PLA active films, followed by the evaluation of its properties. The potential of the ...
